How to make sure my plug boots from the USB flash-stick instead of the USB hard-disk?
My plug is now working very nicely thanks!
It boots from a USB stick. Since it's the only USB mass storage
device, it's /dev/sda.
I'd like to add a USB hub and use it to connect another USB device (a
hard disk) for use as /var, /home, /tmp, and swap.
But then there would be a confusion as to which usb mass storage
device was sda and which sdb, depending on timing.
The usually suggested solution is to mount things by "LABEL=" in /etc/
fstab. But that only tells Linux which to use. It doesn't inform the
boot firmware... Unless I'm missing something.
How do I inform the boot firmware which USB mass storage device it
should boot from?
